摘　　要：结合江西省香炉山钨矿残矿回收工程实践,利用三维有限元数值分析方法,对初步确定的残矿回采顺序与复杂采空区稳定性进行了分析研究,揭示了不同回采顺序下矿柱及采空区的应力分布规律和位移变形趋势,并确定了最优的残矿回采顺序。Based on engineering practice in Xianglushan Tungsten Mine,Optimization of mining sequence in the stoping of remnant ores and stability for complicated Mine area were analyzed by use of 3D Finite element method.the stress distribution and displacement trend were revealed between mining sequenceⅠand mining sequenceⅡ,and the optimization of mining sequence in the stoping of remnant ores was determined.
